... 2.2 Weak Interstellar Scintillation (WISS) When the rms of the phase fluctuations impressed on a wavefront by the ISM between the source and observer are less than a radian, we are in the regime of weak interstellar scattering. ... As the scattering gets stronger, $s_{d}$ decreases and $s_{r}$ increases. ... 2.5 Distribution of Galactic Scattering material Scintillation and angular broadening measurements are used to estimate the spectral coefficient $C_{N}^{2}$ of the electron density power...
